To all whom itmny coiwern':

Beit known that I, Ross E. GARVElKICH, a

citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of "Pennsylvania, have invented a new and useful Railway-Switch, of which the following is a specification. v j This invention relates to railw switchesg its object being to'provide a witch the 19 points or tongues of which are so shaped at their toes as to positively prevent wheel flan es. from working between the 'mainor stool: rail and th ongue, if, from any cause, saidtoes shod not lie firmly'against the i5 rail;

' Another object is to provide a switch tongue, the toe of which is' designed to gradually shift the Wheels laterally from 'the stock or inain rail and on to the tongue, or 20 wice'\"e'rsa,"fthe tread of the tonguebeingin-i clined downwardly toward the toe so astogradually come into contact with the flange of the wheel passing over the switch. i

With these. and otherobjects in view the invention consists of certain novel details of construction and combinationsofparts hereinafter more fully described and pointed. out in the claims.

In the accompanying drawings the preferred form of the intention has been shown. In said drawings:Figure 1 is a plan view of a railway switch embodying the present-improvements. Fig. 2 is-a side elevation, on an enlarged scale, of the toe portion of the switch tongue and of the adjoining portion of the rail, one of the connecting bars being shown in section. Fig. 3- isa-an enlar ed plan view of the'toe portion of the 'switci gtongue, the adjoining rail being 4 broken away, Fig. 4 is a section on line AB Figi-3, a portion of a car wheel being indicated-upon therail and to we Referring to-the figures by c aracters of reference 1, 1 designate the main or stock rails-located at the switch and interposed between these rails are the pivoted tongues -2, each of which has the usual form of heel 3.

The invention in the present case resides in the peculiar form of the toe portion of each tongue and'in the constructlon of the adjoinin portions of the main rails 1. By re erring to Fig. 2 it will be noted that the main rail 1 has its head provided .in its inner face with a longitudinal recess.

' or bulge '7 formed aglal'nst' the rail in Fig. 3, said face 10 gradually merges into 4, arranged-within the bottom portion of the clined as in icated at 5 in Fig. 4: 'so-as to constitute a seat for the inclined upper face 6 of a longitudinally ektending projection ingface of the ton e 2. This bulge is so proportioned that w "en the ton e is shifted 1 said bulge wi l the space between the head and base flange of the rail 1 and will also project into and fill the'recess 4.

iipon the rail-engagcompletely head, the up r'wall of the recess being. i

As shown particularlyin Fig. 2-theupper face of the toe portion of the tongue is 111- clined downwa ly toward the free end of said tongue and vanishes at a point 8, whereit projects into the recess 4, this vanish? point being disposed-below the level of the tread of rail 1. The web 9 of the switch tongue is of uniform thickness, except,

where the bul e 7 is located, and, 'as shown the upstanding faces of the tongue, said upstanding face being inclined or beveled as at 10, the said face being also curved toward the rail 1 at the free end of the tongue,.as shown at 11. This inclinedface 10, which may he termed the guiding face of the switch-tongue, thus projects at its curved end 11 back into the recess 4, and it will be apparent.- therefore that, should the tongue, from any cause, not be shifted firmly against the rail 1, the curved portion-1'1 .of the uiding face will prevent the flanges of the car-wheels from passing between the tongue and the rail-1. The inc ined guidin the tread o the switch tongue.

It is of course to be understood that'both of the tongues 2 are similar inconstruction, the twoton 'ues bei'n as ordinarily, and esigned to be shifted alternately against the respective mile 1. \Vhen the switch is shifted against one of the rails l the bulge 7 upon the adjoining tongue 2 becomes seated between the base flange and the head of the rail 1 and also withinthe longitudinal recess 4, theinclined faces 5 and 6 of the recess and bulge con-- tactingthroughou-t their extent. The curved eIid 11 of the guide face 10 projects between the head and base flange. \Vhen acar uppreaches-the switch the flange of its =first wheel will. first move against the inclined guiding face 10 of the switch tongue at some point along the curved portion 11 of the said face, and said flange will ride upwardly web projects beyond one of connected bybars 12,

' totallyidevoid of all jolting' or pounding the switch tongue is very gradual.

of the tongue and off of the'tread of the rail 1 It will thus be seen that the trans position of the wheel from the main rail 1 to the switch tongue is very gradual and and without danger of the flange of the wheel becoming wed ed between the main k rail andthe tongue. importance is attached to the fact that the initial gradual lateral shifting of the wheel is obtained by the movement of the wheel flangeagainst the inclinedjguiding face 10, and to the further l fact that the contact of the wheel-tire with 2 Obviously, various changes may be made inthe construction and arrangement of the parts without departing from the spirit o'r sacrificing the advantages of the invention.

'What is claimed is l. Amailway switchincluding a recessed main rail, and a movable tongue'having its tread brought to a point remote from the I free end ofthe tongue, the upper surface of i the tongue being inclined downwardly from saidpomt toward the free end, that portion of the tongue between the point and free 1 end being shiftable intothe recess.

2. A"switch including a recessed main rail, and a movable tongue, the tread of which is brought to a point located between the ends of the tongue. that portion of the tongue between the point and the free end 9 of the tongue being inclined downwardly toward said end and shift-able into the recess, said tongue having an inclined .guiding face extending from its free .end and past-the point of thetread.

3. A railway switch includinga recessed main rail, and a movable tongue having a tread forming a point. remote fromlthe free end'of the tongue, th'eupper surface of that portion of the tongue between the pointtfiO and free end being inc'lineddowmvardly toward said end, one side ofthe tongue being inclined for a, portion of its. length toconsti-n tute a gnidingface, said guidingffaeehav ing a convex terminal portion. l

4. A railway switeh including a main rail having a longitudinal recess in thebot tom portion of the head thereof, and-a mov able switch tongue having its tread: brought E to a point located at a distance fronrthdiGO free end of the tongue, that portion .of' the, tongue between the-point-and the said. end

i being inclined downwardly, there being anf inclined guiding face upon thentongue andj terminating at one end in a laterallycurvedf portion, the free end of said tongueian'da" portion of itsv curved guiding face being"; shiftable into therecess. 5. A'railway switch includingsa recessed, main rail, and a tongue having its toe por-":".70

: tion shiftable into the recess, said tongue having means for successively engaging-the? flange and thetread of a wheel passing.ov.e1 oi the switch.

In testin'iony that-I claim the .toregoingastfi 7 my own, I have hereto atfiXed-my signature in the presence of two witnesses. N
